About the company
Computers And Structures, Inc., doing business as C S I, is a self-certified small disadvantaged business based in Walnut Creek, California, that sells structural engineering software licenses and annual maintenance services to federal agencies as a prime contractor. The vendor competes in full-and-open competition without set-asides, though it holds small disadvantaged business certification; across 139 awards tracked in the source data spanning from 2003 to May 2026, CSI operates exclusively as a prime — zero subcontract work appears in its federal portfolio.
CSI's product portfolio centers on three flagship structural analysis platforms: SAP2000 (advanced structural analysis), CSIBridge (bridge design and analysis), and ETABS (building design software). Federal work consists almost entirely of annual software license renewals and maintenance contracts, typically valued between $8,000 and $37,000 per award and running for one-year periods. Representative awards include a $16,135 purchase order from Naval Facilities Engineering Command (NAVFAC) in May 2026 for CSI Cloud Sign-In license maintenance through May 2027, a $37,553 NAVFAC purchase order from May 2025 for cloud sign-in licenses and network maintenance, and an $8,160 Army Corps of Engineers purchase order from April 2025 for SAP2000-4 software license seats under a Total Small Business set-aside. The May 2022 Federal Highway Administration award for annual maintenance of SAP2000 and CSI software was subsequently cancelled; most other awards track to completion without modification.
Customer concentration is moderate and distributed across infrastructure and engineering agencies. The top five customers by award count account for 49% of all awards: the Department of Transportation Federal Highway Administration (17 awards, $308 thousand combined potential value), NAVFAC (17 awards, $187 thousand), Army Corps of Engineers Engineering District Sacramento (15 awards, $193 thousand), Army Corps of Engineers Engineer Research and Development Center (10 awards, $198 thousand), and the Department of the Interior Bureau of Reclamation (9 awards, $55 thousand). The top five by potential value account for 58% of combined dollars and show similar leadership, though Engineer Research and Development Center ranks higher on dollar value than on award count, reflecting larger individual contract values. Across 28 distinct federal customer agencies, CSI serves primarily engineering and infrastructure customers — Corps of Engineers districts and offices, NAVFAC, the Federal Highway Administration, and the Bureau of Reclamation dominate the footprint.
Activity has declined significantly. CSI recorded four awards in 2022, three in 2023, two in 2024, two in 2025, and one as of May 2026. The vendor's combined potential value across all 139 awards is $1.7 million, with $1.8 million obligated — indicating mature, low-velocity maintenance-contract work rather than growth or new platform expansion. Only one award faces recompete within the next twenty-four months, with a combined potential value of $16 thousand. NAICS concentration runs toward Software Publishers (54 awards) and Other Computer Related Services (46 awards); PSC coding emphasizes Information Technology Software (78 awards) and maintenance service plans.
